EPR study of non-covalent spin labeled serum albumin and hemoglobin

Electron Paramagnetic Resonance (EPR) was used to investigate the Tempyo spin label (3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy) as a report group for the interactions and the conformational changes of lyophilized bovine serum albumin (BSA) and bovine hemoglobin (BH), as function of pH values in the range 2.5-11. The EPR spectra are similar with those of other non-covalently spin label porphyrins in frozen solution at very low temperatures. This behavior indicated a possible spin-spin interaction between the hemic iron and the nitroxide group. The changes in the EPR spectra as function of the pH are discussed in terms of conformational changes of the proteins. Spectral simulations and magnetic EPR parameters reveal the following: (i) one single paramagnetic species, with Gaussian line shape, was used for the best fits of experimental spectra in the case of serum albumin samples; and (ii) a weighted sum of Lorentzian and Gaussian line shape in the case of hemoglobin samples. The representation of correlation time vs. pH, reveals a dependence of degree of immobilization of spin label on the conformational changes of proteins in acidic and basic environment.

Transfected adenosine A(1) receptor-mediated modulation of thrombin-stimulated phospholipase C and phospholipase A(2) activity in CHO cells

Thrombin receptor activation in Chinese hamster ovary (CHO) cells stimulates the hydrolysis of inositol phospholipids and the release of arachidonic acid. Our previous studies have shown that activation of the human transfected adenosine A(1) receptor in CHO cells (CHO-A1) potentiates the accumulation of inositol phosphates elicited by endogenous P-2U purinoceptors and CCKA receptors. In this study we have investigated whether adenosine A(1) receptor activation can modulate thrombin-stimulated arachidonic acid release and/or inositol phospholipid hydrolysis in CHO-A1 cells. Thrombin stimulated [H-3]arachidonic acid release and total [H-3]inositol phosphate accumulation in CHO-A1 cells. Both these responses to thrombin were insensitive to pertussis toxin. The protein kinase C activator, phorphbol 12-myristate 13-acetate (PMA), potentiated thrombin-stimulated [H-3]arachidonic acid. In marked contrast, PMA inhibited thrombin-stimulated [H-3]inositol phosphate accumulation. The selective protein kinase C inhibitor Ro 31-8220 (3-{1-[3-(2-isothioureido)propyl]indol-3-yl}-4-(1-methylindol-3-yl)-3-pyrrolin-2,5-dione) had no effect on thrombin-stimulated [H-3]arachidonic acid release but reversed the potentiation of thrombin-stimulated [H-3]arachidonic acid release elicited by PMA. The selective adenosine A(1) receptor agonist N-6-cyclopentyladenosine (CPA) augmented the release of [H-3]arachidonic acid produced by thrombin. Co-activation of the adenosine A(1) receptor also potentiated thrombin-stimulated [H-3]inositol phosphate accumulation. The synergistic interactions between the adenosine A(1) receptor and thrombin were abolished in pertussis-toxin-treated cells. The potentiation of [H-3]arachidonic acid release by CPA was blocked by the protein kinase C inhibitors Ro 31-8220 and GF 109203X (3-[1-[3-(dimethylamino)propyl]-1H-indol-3-yl]-4-(1H-indol-3-yl)-1H-pyrrole-2,5-dione). In conclusion, thrombin receptor activation in CHO-A1 cells stimulates the accumulation of [H-3]inositol phosphates and the release of [H-3]arachidonic acid through pertussis-toxin-insensitive G-proteins. Experiments using PMA suggest that protein kinase C differentially regulates thrombin receptor activation of phospholipase C and phospholipase A(2). Co-activation of the transfected human adenosine A(1) receptor augments thrombin-stimulated phospholipase C and phospholipase A(2) activity. Finally, the augmentation of phospholipase A(2) activity by the adenosine A(1) receptor is inhibited by selective protein kinase C inhibitors, suggesting the involvement of protein kinase C.

Insecticidal, anti-juvenile hormone, and fungicidal activities of organic extracts from different Penicillium species and their isolated active components

Organic extracts from mycelium and culture broth of 21 Penicillium isolates have been tested for insecticidal, insect anti-juvenile hormone (anti-JH), and antifungal activities. Culture broth extracts were the most active, mainly against insects; nearly 25% of them have shown high entomotoxicity (100% mortality at 100 mu g/cm(2)). A strong in vivo anti-JH activity against Oncopeltus fasciatus Dallas was detected in the culture broth extracts from P. brevicompactum P79 and P88 isolates. The two new natural products isolated from P79, N-(2-methyl-3-oxodec-8-enoyl)-2-pyrrolin (1) and 2-hept-5-enyl-3-methyl-4-oxo-6,7,8, 8a-tetrahydro-4H-pyrrolo[2,1-b]-1,3-oxazine (2), possessed anti-SN and insecticidal activity, respectively, against O. fasciatus. Synthesized natural compound 1 has-shown an ED50 of 0.7 mu g/nymph when assayed on newly molted fourth-instar nymphs of O. fasciatus. Promising biological activities have also been detected in the synthetic precursors.

Cross-Linking of Rubber Matrices with Dicumyl Peroxide and Zinc Dimethacrylate. Part I: Effect of Co-Agent Content

The work is focused on the investigation of the influence of the amount of co-agent on cross-linking and properties of rubber compounds. The in-situ radical polymerization of zinc dimethacrylate occurs during the curing process of rubber compounds with organic peroxide. Polymerized zinc dimethacrylate tends to form different types of chemical and physical linkages within the rubber matrices. As the amount of dimethacrylate ranged from 10 to 50 phr, the conversion of zinc dimethacrylate remained low. Residual zinc dimethacrylate formed micro-dispersion in the rubber matrix. The dispersion and distribution of zinc dimethacrylate in the rubber depends on the viscosity of matrix, shear stress and polarity of the matrix. Despite low conversion of zinc dimethacrylate, the application of co-agent resulted in the increase of cross-link density and improvement of physical-mechanical properties of vulcanizates.

An EPR study of wheat seeds by the use of nitroxide spin probes

The viability of a variety of wheat seeds Mas investigated by use of the EPR technique, Three different types of spin probes (4-Hydroxy-TEMPO (TANOL), 3-Carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy, 3-Carbamoyl-PROXYL) were utilized in examining the viability of embryo cells. The penetration of the spin probe across the membrane was observed via the change in signal intensity against time for dry embryos of the variety of wheat seeds soaked in aqueous solutions of spin probe and line broadening agent. From the analysis of the signal intensity-time curves (i.e. rehydration curves) it was observed that the two kinds having different genetic roots (Bezostaya, Kunduru) exhibit similar saturation behaviour whereas Gerek saturates much more easily. The rehydration curves for naturally aged seeds indicates that aging causes rapid saturation and an important decrease in the signal intensity. In order to get better insight on the effect of the signals from polar and nonpolar regions on the experimental spectra, these spectra were simulated by the use of the theoretical models developed.

Late-Stage Transformation of Carboxylic Acids to N-Trifluoroethylimides with Trifluoromethyl Diazomethane

We report the first systematic evaluation of the reaction of trifluoromethyl diazomethane (2,2,2-trifluorodiazoethane, CF3CHN2) with drug-like molecules. We found our previous copper-catalyzed transformation of carboxylic acids to the corresponding N-trifluoroethylimides with CF3CHN2 and acetonitrile is well-suited for the latestage modification of drug and drug-like acids. A procedure that enables the use of solid nitriles and nitriles with high boiling points as viable substrates is also disclosed.
